FAQs on B12 Injections & NAD+ Therapy
What do B12 & NAD+ do?
Vitamin B12 supports red blood cell production, brain health, and energy metabolism. NAD+ (nicotinamide adenine dinucleotide) is essential for cellular repair, mitochondrial function, and natural energy production. Together, they help reduce fatigue, improve focus, and support metabolic health.
How do I get started?
You can purchase a Recharge Kit online or choose à la carte options. NAD+ will be shipped directly to your door. In-clinic B12 injections can be scheduled at your convenience.
How often are injections or supplements needed?
Most clients benefit from a series of weekly B12 injections and daily NAD+ nasal spray (30–35 day supply). Your treatment schedule may vary based on goals such as energy support, metabolic reset, or GLP-1 recovery.
What results can I expect?
Clients often report increased energy, better mood, reduced brain fog, and improved sleep quality. When used as part of a GLP-1 reset or weight loss program, these therapies can enhance metabolism and overall well-being.
Are vitamin-based options safe & are their side effects?
Both treatments are safe when administered under proper supervision. Side effects are rare but may include mild soreness at the injection site or, occasionally, light flushing. No downtime is needed.
